It is my opinion that evolving from normal cat to humanoid sentient being won\'t necessarily make long hair grow on your head.
True, it happened with humans, but what if Enki aestethics are different from humans, which is likely? Also, given that lion
males tend to have longer manes than females, I would expect that to pervail and maybe increase, so the males would IMO be getting long hair, not the females.
Also, I think that long head-hair looks out of place on Enkis, so...
However, there are also those cats with extremely long fur, so there could be Enkis like that as well. They could cut their fur back except on the head, having a hell of a time doing it, but be rewarded with that unique look of Fenki with at least somewhat long head hair.
